need help on: Linux Gnome2 Glade Cairo callback problem

[Mike Durham]

Hi,
I have a Glade project main app window with a toolbar and 4
'drawingarea's, into which I draw some test images using Cairo.
After anywhere between 50 and 100 drawingarea updates I get the
following message when clicking on a toolbar button.

cairo_test_2.rb:147: warning: GRClosure invoking callback: already destroyed

Before the 50-100 drawingarea updates, the callback works fine.
Could anyone possibly tell me, or offer an opinion as to why the
callback is getting destroyed?
All I am doing is updating the drawing areas and clicking on a toolbar
button.

I use Ubuntu Linux, Gnome2, Glade2 and Cairo of course.

Thanks, Mike

I fixed this bug in CVS.

The following patch may solve this bug.

Thanks,

Thanks Kou, your patch fixed the problem perfectly. Just out of
interest, where can I get libglade2.rb 1.14? I don't understand the CVS
thing, where is it?.
Thanks again, Mike

Hi,

Thanks Kou, your patch fixed the problem perfectly.

It's a good news.

Just out of
interest, where can I get libglade2.rb 1.14? I don't understand the CVS
thing, where is it?.

See http://sourceforge.net/cvs/?group_id=53614.

In this case, you will type the following command:
% cvs -z3 -dserver:[email protected]:/cvsroot/ruby-gnome2
co -P ruby-gnome2/libglade

Thanks,
